Reactivity towards beta elimination
WebAnswer: Tertiary alkyl halides are generally more reactive towards elimination than substitution. This is due to the steric hindrance when a tertiary alkyl halide is subject to nucleophilic attack: the nucleophile will have a lot of difficulty attacking the carbon atom in question due to its high... WebBeta-hydride elimination is a reaction in which an alkyl group having a . β. hydrogen, σ. bonded to a metal centre is converted into the corresponding metal-bonded hydride and a . π. bonded alkene. The alkyl must have hydrogens on the beta carbon. For instance butyl groups can undergo this reaction but methyl groups cannot. The

Both iridium and cobalt are found to be active towards … WebThe reaction follows Zaitsev's rule, giving the more highly substituted alkene as the major product. Beta-elimination of a vinyl bromide using sodamide (NaNH 2; (a strong base) as the base forms an alkyne.
WebBy using the strongly basic hydroxide nucleophile, we direct these reactions toward elimination. In both cases there are two different sets of beta-hydrogens available to the elimination reaction (these are colored red and magenta and the alpha carbon is blue). If the rate of each possible elimination was the same, we might expect the amounts ... WebSolution: More the number of β -substituents (alkyl groups), more stable alkene it will form on β -elimination and more will be the reactivity. Thus, the decreasing order of the rate of β -elimination reaction with alcoholic K OH is : I > III > II
